The Pass Lake is a zinc, molybdenum, and copper mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Reference): Primary Reference = Resource Associates of Alaska
Comment (Workings): Workings / Exploration = Reconnaissance surface observation and sampling has been completed in this area.
Comment (Geology): Geologic Description = This occurrence represents an approximately 5-square-mile area of local base metal geochemical anomalies (Resource Associates of Alaska, 1976). At the map site, Tertiary biotite granite float containing disseminated molybdenite assayed 960 ppm molybdenum. Tertiary granite throughout the area locally contains molybdenite, pyrite, and pyrrhotite, and, less commonly, chalcopyrite and sphalerite. At least some of the mineralization is probably in quartz veins.
Comment (Deposit): Other Comments = This occurrence is within Lake Clark National Park.
Comment (Deposit): Model Name = Porphyry Cu-Mo (Cox and Singer, 1986, model 21a)
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary. Sulfide mineralization is in Tertiary granitic rocks.
